So I just installed windows 7 x64 (bootcamp) on my iMac 27" mid 2010. It seems to be taking up 11 GB more than there really is on the partition. Partition size: 33 GB Used space: 22 GB (in reality 11 GB) Free space: 11 GB (in reality 22 GB) I know for a fact that a newly installed windows 7 is not this huge. Also I selected all the folders and checked the size and it simply doesn't match what the Drive Properties tells me. Is there anyway to fix this?
